Motihari-Amlekhgunj Petroleum Pipeline

The Motihari-Amlekhgunj Petroleum Pipeline is South Asia's first cross-border fuel pipeline, connecting a railhead terminal at Motihari in the East Champaran district of Bihar to a depot at Amlekhgunj in Nepal's Bara district. Its legal and institutional foundation rests on a bilateral memorandum of understanding signed in August 2015 during Indian Prime Minister Narendra Modi's visit to Nepal, which committed the two governments to constructing a dedicated petroleum products pipeline. The project was executed under an arrangement between Indian Oil Corporation Limited (IOCL) and the Nepal Oil Corporation (NOC), the state monopoly importer of petroleum into Nepal, building upon the longstanding commercial relationship under which NOC procures all of Nepal's refined fuel from IOCL. The framework also draws on the India-Nepal Treaty of Trade and the broader transit and supply understandings that govern landlocked Nepal's dependence on Indian refineries and ports.

The operational mechanics are straightforward but historically significant. Refined petroleum products—principally diesel, petrol, and kerosene—are railed to the IOCL terminal at Motihari, from where they are pumped through the 69-kilometre, roughly 10-inch-diameter pipeline across the international border into the receiving terminal and storage depot at Amlekhgunj. The pipeline has a design throughput capacity of approximately two million tonnes per annum, far exceeding current Nepalese consumption drawn through it, which provides substantial headroom for demand growth. Fuel arriving at Amlekhgunj is then distributed onward by NOC's tanker fleet to depots and retail outlets across central and eastern Nepal, including the Kathmandu valley.

Before the pipeline became operational, all of Nepal's imported fuel moved by road tanker—thousands of trucks queuing at the Raxaul-Birgunj crossing and hauling product up the hill roads. The pipeline displaces a large share of this tanker traffic, cutting transportation costs (NOC and IOCL projected savings of several rupees per litre), reducing pilferage and adulteration, eliminating the long tanker queues at the border, and curbing carbon emissions and road wear. It also insulates supply from the kind of disruption witnessed during the 2015 border blockade, when fuel shortages crippled Nepal and underscored the strategic vulnerability of an exclusively road-based supply chain. The pipeline was completed substantially ahead of its original schedule, in part because India accelerated work after that crisis.

The pipeline was jointly inaugurated via video conference on 10 September 2019 by Prime Minister Narendra Modi and Nepalese Prime Minister K. P. Sharma Oli, making it the first transnational petroleum pipeline in South Asia. Construction was driven from New Delhi through the Ministry of External Affairs and the Ministry of Petroleum and Natural Gas alongside IOCL, and on the Nepalese side through the Ministry of Industry, Commerce and Supplies and NOC. Following the success of the first phase, the two sides agreed to extend the network: a planned extension northward from Amlekhgunj toward Lothar/Chitwan and the Kathmandu valley, and a second pipeline corridor in eastern Nepal from Siliguri in West Bengal to Jhapa, were taken up to deepen Nepal's pipeline-based fuel security.

The Motihari-Amlekhgunj pipeline should be distinguished from broader India-Nepal connectivity instruments with which it is sometimes conflated. It is a petroleum products pipeline, not a crude pipeline and not a natural gas line, and it is therefore unrelated to gas-grid diplomacy. It differs from cross-border rail links such as the Jaynagar-Janakpur-Bardibas line or the Raxaul-Kathmandu broad-gauge survey, and from the integrated check posts (ICPs) at Birgunj and Biratnagar, which handle general cargo and people. It is also separate from the hydropower and electricity-trade dimension of the bilateral relationship governed by the 2014 Power Trade Agreement. What unites these strands is the concept of physical connectivity as an instrument of statecraft, but the pipeline's specific function is single-commodity fuel logistics.

The project sits within a contested strategic context. Nepal pursues a policy of balancing between India and China, and Beijing has explored its own fuel-supply overtures to Kathmandu, including a 2017 memorandum on petroleum supply through the Tibetan corridor, which would diversify Nepal away from total Indian dependence. Critics in Nepal periodically frame near-exclusive reliance on IOCL as a vulnerability, while Indian analysts present the pipeline as a tangible, low-controversy deliverable that builds goodwill without the friction attached to disputed issues such as the Kalapani-Lipulekh-Limpiyadhura boundary or the 2020 map dispute. Pricing and supply terms remain negotiated commercially between NOC and IOCL and have occasionally generated domestic Nepalese debate over transparency, but the pipeline itself is widely regarded as a model success in bilateral infrastructure cooperation.

For the working practitioner—whether a desk officer, a UPSC General Studies Paper II aspirant, or a connectivity analyst—the Motihari-Amlekhgunj pipeline is a compact case study in how infrastructure diplomacy operates between a landlocked state and its transit neighbour. It illustrates the interplay of energy security, commercial state monopolies, post-crisis policy acceleration after the 2015 blockade, and competitive influence dynamics with China. It is frequently cited as evidence of India's Neighbourhood First policy producing concrete, completed outcomes rather than aspirational pledges, and it offers a tangible reference point when assessing the durability of India-Nepal relations against the backdrop of recurring boundary and nationalist tensions.
